We have about fourty users here and at the moment are only using a DSL router and NAT for protection. We have finaly talked the partners into getting a decent firewall. One of our consultants says MS ISA is the way to go. Another says his company has had nothing but trouble with MS ISA and they switched to Esoft's Instagate EX2 and they love it. Easy to setup and manage.
Does anyone have an opinion on this or a suggestion on a better firewall?
We are running W2K Servers, Exchange 5.5 (soon to be exchange 2000), DSL for internet access.
Our wants are to have the most secure firewall we can get for under $2500 - $3000. We would like to be able to block just a few specific sites.
Thanks for your advice in advance,
